Package com.saxonica.functions.extfn
package com.saxonica.functions.extfn
The package com.saxonica.functions.extfn contains implementations of extension
functions in the Saxon namespace.
It also contains the class VendorFunctionSetPE which acts as a factory class for
generating instances of these extension functions.
These extension functions are implemented using a variety of mechanisms. Some are implemented in the same way as system functions. Some use the "integrated extension function" mechanism introduced in Saxon 9.2.
